Guest zenkinz Posted June 30, 2010 Report Share Posted June 30, 2010 (edited) They've kinda done that already, if you have a look around dbdata. There's other partitions that seem to be unmounted, gonna look into what they are for... P ok I saw that. but it's for db. maybe we can try with those core apps with huge cache/file in /data/data first, and i noticed its namely the com.android.providers/emails, imes and maybe the launcher. now I am wondering, Galaxy S has 512MB RAM, 2G ROM and 16G internal storage. I see that the 16G internal storage is mounted on /sdcard and 2G ROM apparently has been partitition into multiple blocks and mounted as folders such as /system and /data ? If so, what's rootfs (and the fs that mounts dbdata?) part of the 512MB RAM? Edited June 30, 2010 by zenkinz Link to comment Share on other sites More sharing options...
Guest Toreak Posted June 30, 2010 Report Share Posted June 30, 2010 Check your /data/data first to see which apps are storing lots of data in the megabyte range. Here's how: adb shell su cd /data/data busybox du -h|busybox grep M games like gameloft games do take a few Mbs and google earth took about 20Mb. Unless there are new workarounds, the easiest way right now is to uninstall those apps that u can do without that takes up megs of space in /data/data. Alternative is try to identify apps that cause the stall and create symbolic links for those apps' data to /dbdata Link to comment Share on other sites More sharing options...
Guest KUNG_C Posted June 30, 2010 Report Share Posted June 30, 2010 (edited) THANKS TO PAUL! I've already done it, the phone is super fast now. But i also want to know, can the new apps install to /data/data again? instead of /dbdata/data like to fuction App2SD Edited June 30, 2010 by KUNG_C Link to comment Share on other sites More sharing options...

Guest ragflan Posted June 30, 2010 Report Share Posted June 30, 2010 Paul, you've had the Desire and now the Galaxy S, which device would you recommend for performance. I heard The Galaxy had better performance in terms both CPU usage and graphics in games. Besides the obvious advantage of a larger and better screen and ignoring touchwiz vs sense, which phone would yousay performs better? Thanks in advance Paul. I ask because I wanted to get Droid X but I heard that its for US only and I'm in Australia. So either desire or galaxy are the best options ...

Guest us1111 Posted June 30, 2010 Report Share Posted June 30, 2010 (edited) If you have a fast (>=class 6) sdcard, wouldn't it be an option to place the files there? I did not have time to root my phone, but you could use (i.e.) hdparm to check the speed of your external memory and then choose where to put the files..

Although accesstime is more important than speed in this case. Is there someone out there who could run some accestime tests on the internal sd versus s a class 6 card?

Guest Shibby_nl Posted June 30, 2010 Report Share Posted June 30, 2010 I have read some different experiences from users, mysef included. I can't notice any lags, it is my first android though. I don't have any experience to compare with. Isn't it also possible that there are different types of internal sdmemory installed? The fast one's were out of stock that batch? So maybe a speedtest is needed with a standard program. Does anyone know a suiteble app for this? Link to comment Share on other sites More sharing options...

Used the program from android market called J BenchMark 1.0. I compared the internal NAND flash to the sd-card that I put in (just a plane old regular 1GB card). Maybe some one can test on a different device. I'm not sure which part of the NAND it's testing as there are just options for internal or external sd. I tested 4 times each, differs about 10%.

Guest VarunRai Posted June 30, 2010 Report Share Posted June 30, 2010 (edited) Hi! So I've rooted my SGS and got folder sizes of folders in /data/data. Here's what it looks like : 1.5M /data/data/com.google.android.apps.maps/files 1.5M /data/data/com.google.android.apps.maps 9.5M /data/data/com.sec.android.app.sns/files/ReceivedFiles 9.5M /data/data/com.sec.android.app.sns/files 9.5M /data/data/com.sec.android.app.sns 4.3M /data/data/com.sec.android.app.samsungapps/cache 4.3M /data/data/com.sec.android.app.samsungapps 1.9M /data/data/com.swype.android.inputmethod/swypedata/Tutorial 2.9M /data/data/com.swype.android.inputmethod/swypedata 3.0M /data/data/com.swype.android.inputmethod 0 /data/data/com.android.MtpApplication/lib 0 /data/data/com.android.MtpApplication 2.5M /data/data/com.sec.android.widgetapp.feedsandupdate/cache 2.5M /data/data/com.sec.android.widgetapp.feedsandupdate 6.3M /data/data/com.android.vending/cache 6.3M /data/data/com.android.vending 1.1M /data/data/com.google.android.youtube/cache 1.1M /data/data/com.google.android.youtube 1.8M /data/data/com.gameloft.android.GAND.GloftAsphalt5.asphalt5/lib 2.3M /data/data/com.gameloft.android.GAND.GloftAsphalt5.asphalt5 1.9M /data/data/com.glu.android.skob2_free/lib 82.8M /data/data/com.glu.android.skob2_free/app_save 85.8M /data/data/com.glu.android.skob2_free 121.6M /data/data Could someone please explain what sns is and why it's taking so much space. Or maybe suggest something I could do to reduce the space. I understand that I haven't yet reached the 130 mb mark, but if I did make the mod as suggested in the first post, would'nt having a smaller size of /data/data be better?? Or does it not make any difference once I've made the move? And Paul, thank you so much! This was a much needed mod! EDIT : Just removed a silly game which had loaded resource files on my phone memory. Down to 39 MB now. Will update on phone speed after using it tomorrow. :lol: Also, it's time I got an SD card. EDIT 2 : Paul, small question. If we continue adding apps, what happens to the data that they store? Does it get saved in phone memory or NAND?

Guest jUsT2eXy Posted June 30, 2010 Report Share Posted June 30, 2010 (edited) hey guys.. i followed this method but I get a 'low on space - database storage is getting low- warning" ...nks what do I do now?

Guest jhansen Posted June 30, 2010 Report Share Posted June 30, 2010 Try at your own risk... if things go wrong you'll need to wipe your device. I have done this and it seems to have eradicated the 'stalling' i've seen on the device... Nice discovery! this made a world of difference, now the device is usable :lol: Samsung must have messed something up badly. Link to comment Share on other sites More sharing options...

I guess the reason this happened is because I don't know how to find out how much space data or dbdata uses... how do I find out? thanks You need to either reverse the operation (reuse the /data/data.bak) or do a selective linking to some of the bigger files to the sdcard both methods have been discussed in this thread Arnon Link to comment Share on other sites More sharing options...

Guest Kilack Posted June 30, 2010 Report Share Posted June 30, 2010 Hi, I have just got one of these and probably wouldn't have if I had read about the lag issues etc before hand. Is it looking like it is a hardware issue and they just used poor internal storage? in which case there isn't much that can be done apart from little workarounds to try and ease it a little... Or is it a firmware issue? Some are suggesting its a memory leak in touchwiz.... Has anyone heard if Samsung have said anything about these issues?
